- Flexible instrument configuration with a variety of light sources (laser diodes, LEDs and Ti:Sapphire laser)
- A compact footprint and short optical path length for maximum sensitivity and efficient light coupling into the sample
- Second to picosecond lifetime measurement capabilities
- Full automation of instrument components including: cuvette holder, polarizers, shutters, filterwheel, monochromators and stirrers
- PC-controlled integration of temperature path, titrator, stopped-flow apparatus and pressure pump
- Upgradable to a full steady-state instrument
- T-format and parallel beam optical design for fast and precise polarization measurements
- Powered by Vinci-Multidimensional Fluorescence Spectroscopy
- Fluorescence lifetime is calculated from two measureable parameters: phase angle and modulation
- Is a faster and less artifact-prone
- Allows one step measurements of anisotropy decays (rotational correlation times)
- Is better at resolving short lifetime contributions
- Is the method of choice for lifetime-based sensing and real-time measurements because of high sampling rates in the millisecond time scale
